CENTRIFUGAL MIXING APPARATUS.

which comprises a vane wheel and a pipe fixed to and rotating with it, in which, owing to the centrifugal action of the vane Wheel, a powerful suction effect and consequently a vigorous circulation of the mass passing over the edge of the pipe are produced.

The invention resides in the provision in the suction pipe fixed .to the vane wheel' of a pipe telescopically displaceable in it and if necessary of another such pipe and so forth in order to enable the topmost edge of the pipe to be adjusted to the level of the mass under treatment.

In the accompanying drawing :-Figure 1 re resents a vertical section throu h the middle of the apparatus. Figs. 2 an 3 are plan views of the upper and the lower inclosing plates of the vane wheel respectively on slightly larger scale.

The vane wheel d is fixed on a vertical shaft 0 driven by transmission gear b and arranged in the vessel a. This vane wheel consists of the upper and lower inolosin plates 6, f and a number, say four, radia walls fixed between these plates, forming the vanes g and constituting the four closedwheel-chambers 1 to 4 separated one from The lower lnclosing plate f stands somewhat away from the bottom of the vessel or and in one of the chambers, say the chamber 1, it is provided in proximity to the shaft 0 with a recess it through which during the rotation of the vane wheel a suction effect in the upward direction is produced, that is to say a circulation of the mass standing on the bottom through the corresponding chamber of the vane wheel to- "ward the exterior and over the bottom, so

that, when the mass contains solid constituents, they are constantly agitated in settling and mixed with the mass. Theother three chambers 2, 3, and 4 of the vane wheel are in communication with the interior of the pipe k-arranged upon and rotating with I Specification of Letters Patent. Patented Apr. 12, 1910.

the vane wheel, by means of a recess i in the upper inclosing plate e; during the rotation o of the vessel a prevent rotation of the mass contained in the vessel around the shaft 0.

Theparts described above are known and do not constitute the essence of the present invention which consists in the fact that in the pipe another ipe n displaceable telescopically is arran e In the pipe'n'still another telescopicalIy displaceable pipe (not here shown) can be mounted. The same object can be attained by arranging the ipe 11 outside the pipe is and the free width of the suction pipe may increase stepwise toward its upper part.

The adjustment is conveniently effected by means of a gear wheel p mounted on a shaft 0 journaled in the wall of the vessel; this gear wheel meshes -with the upper toothed part of the pipe 11.. As the pipe it rotates the teeth formed around its upper part make it possible to adjust the edge of a section suction pipe rotatable with the wheel, and means whereby said suction pipe may be adjiistably extended orcollapsed during the rotation thereof.

2. In a device of the type set forth, in

combination with a vane wheel having chambers, a collapsible and extensible suction pipe rotatable with said wheel and communicating with said chambers, a vessel vwithin which said parts are mounted, and

means carried by the vessel and engaging said pipe whereby the latter may be extended or collapsed during rotation thereof.

3. In a device of the type set forth,in'

combination with a vane wheel divided into 7 chambers, a multi-section suction pipe ro tat-able with the wheel, the uppermost of the sections of said pipe being ormed with a series of annular teeth, and a rotatable gear meshing with said teeth and adapted upon rotation thereof to extend or collapse of a plurality of telescopic sections, a vessel in which said parts are mounted, and rotatable means carried by sald vessel anden;

gaging one of the sections whereby by rota 1(.

tion of said means said section may be adjusted.

In witness whereof I have hereunto set my hand in presence of two witnesses.
